Rocky Mountain Project?Probable Maximum Floods
Probable maximum floods (PMF's) were estimated for use in designing spillways for the lower reservoir main dam and two auxiliary pool dams at the Rocky Mountain pumped-storage...
Validation Studies on Indexed Sequential Modeling for the Colorado River Basin
A method called indexed sequential modeling (ISM) has been developed by the Western Area Power Administration to estimate reliable levels of project dependable power capacity (PDC) and...
Operation of Hydropower Plants Considering Daily Streamflows
Operation of hydropower plants is a sequential decision process often modeled as a dynamic programming problem. Typically, such formulations consider monthly stages assuming that monthly...
Streamflow Gaging in a Remote Area Using Cellular Telephone Telemetry
A case study will be presented describing the utilization of cellular phone technology in a remote sensing situation. Because expected annual energy estimates are vital in planning small...
An Artificial Intelligence Approach to Multiple Reservoir Operation
The modeling of complex river basins using symbolic computer languages, object-oriented programming and knowledge-based reasoning facilitates, the application of optimization techniques...
Evaluating Hydro Project Benefits with the POWRSYM Production Cost Model
The contribution that a hydro peaking project or pumped-storage project makes to reducing system operating costs can be determined only by modeling the project's operation...
Colorado River Probable Maximum Floods
Upper limit design rainstorms (ULDRS) were developed for three locations in the Colorado River drainage above Hoover Dam. For each location, the rainfall magnitudes, spatial and temporal...
Penstock Monitoring System in Active Landslide Areas
During initial planning of a high-head, five megawatt hydroelectric plant in Northern California, it was identified that the entire three-mile length of a 40 inches welded steel penstock...
Waterpower 91?Laboratory Investigation of Syphon Intakes
The Federal Department of Energy, Mines and Resources (Canada) has funded four separate investigations of syphon hydro technology. These study phases, which were carried out by Acres Hydraulic...
Fish Bypass System Mathematical Models
Mathematical models for fish diversion systems based on fish behavior in conjunction with diversion system structural and hydraulic properties are developed. Guidance efficiency is described...
An Overview of the Latest Developments in the Modernization, Upgrading and Rehabilitation of Existing Hydraulic Turbines
The growth experienced in the 1980's in the modernization of older hydro plants has fueled the development of new runner and wheelcase designs and modifications providing...
Pressure-Time Method Using Modern Practices
Over the past twenty years, Hydro-Quebec has modernized the pressure-time method of flow measurement, a method which is generally economical but sometimes difficult to apply. Starting...
Application of Personal Computers to Field Flow Measurement
Flow measurements are often necessary to verify the performance of hydro turbines for regulatory, contractual, or engineering purposes. Historically, several methods utilizing various...
Australian Lysimeter Studies of Field Evaporation
Evaporation data are summarised from separate lysimeter installations involving forest, crops and pastures along the 35?S parallel in south-eastern Australia. In each study, lysimeter...
Lysimeters: Data Acquisition and Analysis
Lysimeters provide the most direct method for measuring evapotranspiration (ET). For ten years we have used weighing lysimeters capable of a resolution equivalent to 0.02 mm of water....
Representativeness of Floating Evapotranspirometers
